在sql中获取月度报告

Question

我输入了我的数据库列日志，数据，类型 如何从一年后开始获取日志与月份区别 柔性： 行

logs = 'error...'
data = 2012-11-05 11:24:08
type = 1

.... 我希望在那个视图中得到它们

month     logs-count   type
January     100         1
January     100         2
February    160         1
February    120         2
 ....

Answer 1

试试这个，如果这些列在同一个表中

select monthname(data) as month,count(logs)as logs-count,type from table
 group by month

Answer 2

试试这个：

select datename(month, data) as month count(logs)as logscount, type from table

Answer 3

对于mysql：

select monthname(data) as month, count(*) as logs-count, type
  from table
  group by month, type

您需要按日期和类型进行分组，以便每月获得多行。
